Current forecast models from sources including GFS show Shanghai under stable high pressure with light northeast winds and mostly clear skies overnight into September 13, supporting strong radiative cooling and a minimum temperature consensus near 22–23°C. Official guidance and ensemble runs cluster tightly around this range, consistent with September climatology of 20°C average lows, while minimal cloud cover or moisture advection reduces upside risk for warmer readings. The market's heavy weighting toward 23°C (57.5%) and 24°C (28%) reflects this model agreement and limited variability expected before resolution, with lower-probability cooler outcomes requiring an unforecasted shift in steering patterns or boundary-layer conditions. Updated model runs tonight will provide the final refinement ahead of the overnight minimum.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zspd
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
